I took my 1994 325is in to my BMW dealer with the following symptom:
rough engine behaviour when starting cold , but once warmed up , sounds
after a numbe of 'standard' tests turned up nothing, they did a
compression test and came up with the following numbers ( which I
confess I have no idea re the meaning of:
leakage% 1 2 35 4 5 6
They said this cylinder 3's leakdown was not acceptable and that they
recommended an engine rebuild or replacement dur to 'suspected wear on
engine bottom end'.
I am your typical BMW owner I suppose because I seem to be unable to
sort thru all this, but I can't help but wonder if they are not giving
me a cheaper alternative because they want the 20 hours of labour at
$110/hr to put the new engine in.
I would really appreciate it if someone who understands what could be
going on in my engine could answer a few questions, like: Could this
really be the cause of my original complaint? what is 'suspected wear
on engine bottom end/? and , is there no cheaper alternative open?
One PS I must add is that 9 months ago I paid a non-BMW dealer $2600 to
fix a 'crack' in the engine block. I am about to take it back to him
and ask whether this purported oil problem is related to the work he
did. You can guess what his response will be. Can you offer any
suggestions on how I can approach this guy to avoid getting hosed by
him as well? Do you think there could be a connection between the two?
Many thanks in advance to anyone who takes the time to comment. I value
your opinions, believe me.
